Well nobody likes bugs right. I try not to kill anything if I dont have to nowdays. But a fear of mine has always been the prospect of getting bitten by something that I have just nuked with flyspray. If you were to be spraying allover a wasp or small creature, and then suddenly the tables turned and you got a little taste of your own medicine... Would you become more poisoned because there is now flyspray all over said individual that is now attacking you?
i doubt it would be enough to harm you. and just light the bug on fire after its full of buspray anyways.
